WASHING MACHINE.

Application filed July 2,

To all whom it may concern:

Be it known that I, MAUDE B. LATSHAW, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Vashing Machine, of which the followingis a specification.

My invention consists of a washing machine embodying a beater mechanismfor raising, lowering and rotating the latter, and

the provision of chambers in said heater where the clothes or articlesto be washed are subjected to the pressure of air in said chambers, aswell as the members of the beater itself, provision being further madefor relieving said chambers of the excess of air in said chambers andforming vacuums in thelatter so as to permit the heater to descend inthe water to the extent of its motion so as to be eased in said motions.

The invention is satisfactorily illustrated in the accompanying drawing,but the important instrumentalities thereof may be varied, and so it isto be understood that the invention is not limited to the specificdetails shown and described, as long as they are within the scope of theclaims.

Figure 1 represents a vertical section of a washing machine embodying myinvention. Figure 2 is a perspective view of the lower mechanism of thedevice on an en larged scale.

Figure 3 represents a partial side elevationand partial vertical sectionon line 3-3 Figure 2.

Figure 4 represents a vertical section of the beater and appurtenanceson an enlarged scale.

Figure 5 represents a horizontal section on line 55 Figure 4.

Figure 6 represents a perspective view of the beater on a reduced scale.

Figure 7 represents a transverse section of a portion on line 77 Figure5.

Figure 8 represents a vertical section of a portion detached from theright hand side of Figure 1.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings,

1 designates a tub of suitable construction, and 2 designates a beatertherein, said beater being connected with the rotatable and verticallymovable shaft 3 which depends from the heater and is passed through anopening 4 in the bottom 5 of the tub and 1923. Serial No. 648,862.

extends below said bottom where it has secured to it the ratchet 6 whoseteeth are adapted to be engaged by the pawl 7 which is mounted on theyoke 8, the inner end of the latter being secured to the collar 9 whichfreely encircles the shaft 3. Connected with said collar is the arm 10on whose terminal is mounted the toggle-like lever 11 which depends fromsaid terminal and with whose limbs are Pivotally connected one of theswinging arms 12. Another swinging arm 12 is pivotally connected withthe link 13 which latter and the lower limb of the toggle like lever 11have their axes 14: on the bracket 15 which is secured to and dependsfrom the table 16 on which the tub 1 is supported.

Pivotally connected with the lower limb of the toggle like lever 11 andwith the lower end of the link 13 are the elbows 17 which rise from thecross head 18, the latter having centrally in it an opening throughwhich passes freely the reduced neck 19 on the lower end of the shaft 3,said neck founing at the top the shoulder 20 against which bears freelythe central portion of the cross head 18 whereby when the latter israised it bears upwardly against the shoulder 20 and so elevates theshaft 3. Then as the pawl 7 and ratchet 6 are operated rotary motion isimparted to said shaft, the heater 2 following the motions of saidshaft, as will be hereinafter more fully described.

Motion may be imparted to the arms 12 by means of an electric motor 21whose shaft with the arms 12, and thus said arms will receive rising andlowering motions which are assisted. by the spring 12 which is connectedwith said arms and the adjacent support 21 for the motor 21.

The beater 1 is a concave body, the central portion of which has thereinthe vertical walls 24 and 25, which are connected at the top by the wall26, said walls being separated forming the circular air and waterreceiving chamber 27. The Wall 21 is connected with the centralhorizontal wall 28 in which is an opening 29 for the reception of theadjacent portion of the shaft 3, around which opening rises the collar30 which is bolted or screwed to said wall 28 and is socured to saidshaft 3 by the pin 31 which is passed through said shaft and collar.

In the upper end of the wall 25 are ports 32 for the exit of excess airand water in the chamber 27., The walls 24 and 28 form. the centralchamber 33 for the reception of air and water, it being noticed that thelower end of the chambers 27 v and 3a are open at their lower ends so asto be in communication with the interior of the tub 1.

Connected with the wall 28 is the tubular nipple 3a which opens into thechamber 33 and is connected with the chamber 35 containing thespringpressed valve 36, and a seat therefor, said valve chamber havingports for the escape or the excess of air and water entering the chamber33.

Extending laterally trom'the wall 28 of the chamber 27 are the wings 37which are.

hollow torming the chambers 38 therein.

Connected with the upper walls of said wings by suitable nipples are thechambers 39, the same containing the spring pressed valves 39, seatstherefor, and ports 4=O for the escape of the excess of air and waterfrom said chambers 39.

it will be noticed that the valve, etc., for

the chambers 33 shown in Figure 4 are substantially the same as theconstruction shown in Figure 8 for the wings 37 on an enlarged scale.

The operation is as follows, the tub having been properly supplied withwater and soap,as in Figure 1 The arms 12 recelve up and down movementsfrom the motor 21, and so causes the toggle like levers 11 to open andclose usual QThe beater, thus rotating then enters the ing noticed thatthe air in the several chambers of the beater also press against thewater and rotates and agitates it and'the suds therein. The clothes orother articles in the tub are carried around in the water and suds andhighly subjected to the pressure or pounding action of the beater, it bewater-in the tub and the articles that are being washed therein and soassist in-pressing and pounding said articles.

Now it is important to relieve the excess of pressure of the air andwater in the chambers when the closing action of the valves is overcomeand the latter are opened, and so the said excess escapes from the valvechambers and causes vacuums in said chambers, thus allowing the beaterto descend more readily to a requisite extent in the nesaesa water andsuds. Then thebeater rises and descends when it turns and engages thearticles at diflerent places and further rotates the latter in the waterand thusefiectively washes the articles.

Having thus described my invention what I claim asnew and desire'tosecure by Letters Patent, is

1.. In a washing machine, a beater, a rotatable and vertically movableshatt carrying said beater, a tub in which said heater is operative,said heater being formed of a body provided with a central chamber, asecond chamber surrounding the central chamber, an auxiliary chambersurrounding said second mentioned chamber, and wings extending from saidauxiliary chamber, said wings having chambers therein, the severalchambers being open below in communication with the interior of the tub,and means for relieving said chambers of vacuum.

2. In a washing machine, a beater, a shaft carrying said heater, a tubin which said beater is operative, means for rotating, lowering andraising said shaft and beater, said beater being formed of a bodyprovided with a central annular chamber, a second annular chambersurrounding the central chamber, an auxiliary chamber surrounding saidsecond mentioned chamber, and wings extending from said auxiliarychamber, said wings having chambers therein, the several chambers beingopen below in communica tion with the interior of the tub, and means forrelieving said chambers of vacuuin.
